Description

Technical Field

[0001] This invention relates to the field of belt slitting machine technology, and in particular to an automatic belt slitting loading and unloading device. Background Technology

[0002] Grinding machines typically use two types of abrasives: grinding wheels and abrasive belts. Abrasive belts are coated abrasives, also known as flexible abrasives. They are strip-shaped tools made by bonding abrasive particles to flexible materials such as paper or cloth using an adhesive, allowing for grinding and polishing. Abrasive belts are more flexible and safer than solid grinding wheels during polishing, and also offer advantages such as high precision and low grinding costs. Annular abrasive belts are a type of abrasive belt, and manufactured annular abrasive belts are usually quite wide. To facilitate grinding with annular abrasive belts, they are typically slitting using a slitting machine.

[0003] Currently, a patent document with authorization announcement number CN207788692U discloses a ring-shaped abrasive belt slitting machine, which solves the problem of low efficiency in common manual methods of cutting ring-shaped abrasive belts. The key technical points of the solution include: a frame; a first positioning roller and a second positioning roller rotatably connected to the frame for the ring-shaped abrasive belt to be fitted onto; a first driving mechanism for driving the second positioning roller to approach or move away from the first positioning roller; a second driving mechanism for driving the first positioning roller to rotate; a cutter roller; and a third driving mechanism for driving the cutter roller to rotate so that the cutter roller approaches or moves away from the first positioning roller. The first positioning roller has a cutting groove for the cutter roller to partially insert into, allowing the cutter roller to completely cut the ring-shaped abrasive belt, thus achieving efficient cutting of the ring-shaped abrasive belt.

[0004] However, in actual use, the operator needs to place the annular sanding belt onto the first positioning roller and the second positioning roller. After the cutting roller cuts the annular sanding belt into strip annular sanding belts, the operator also needs to remove the strip annular sanding belts from the first positioning roller and the second positioning roller. Manual loading and unloading requires long hours of operation in the work area, which is labor-intensive. Therefore, we have proposed an automatic sanding belt slitting and unloading equipment to solve the above problems. Summary of the Invention

[0025] 4. The electric push rod can drive the adjusting roller to move, thereby adjusting the distance between the adjusting roller and the rotating roller, thus achieving the purpose of tightening the sanding belt. The rotating roller can drive the sanding belt to rotate. The cutter roller in the slitting mechanism approaches the rotating roller, thereby achieving the purpose of dividing the sanding belt into multiple strip-shaped annular sanding belts.

[0026] 5. After the slitting is completed, the reduction motor can drive the feeding push plate to move back and forth. When the feeding push plate moves forward, it can push the slitting strips of annular sand belts off the rotating roller and adjusting roller, so that the strips of annular sand belts can fall into the collection box. When the feeding push plate moves backward, it can reset the feeding push plate, thereby achieving the purpose of feeding multiple strips of annular sand belts. Attached Figure Description

The arc-shaped clamping plate 20 can squeeze the sanding belt 4. Since the sanding belt 4 is elliptical, the squeezing will cause the middle to bulge.

[0045] By starting the rotary motor 29, the rotary motor 29 can drive the threaded rod 28 to rotate, the threaded rod 28 can drive the movable seat 27 to move, the movable seat 27 can drive the feeding push plate 31 to move, the feeding push plate 31 can drive the pushing shell 501 and the sanding belt 4 to move, so that the sanding belt 4 with the middle bulge is pushed onto the rotating roller 35 and the adjusting roller 36. By starting the electric push rod 45, the electric push rod 45 can drive the sliding seat 43 to move, the sliding seat 43 can drive the adjusting roller 36 to move through the fixed seat 44, thereby adjusting the distance between the adjusting roller 36 and the rotating roller 35, thereby achieving the purpose of tightening the sanding belt 4. The rotating roller 35 can drive the sanding belt 4 to rotate. By the cutter roller in the cutting mechanism 39 approaching the rotating roller 35, the sanding belt 4 can be divided into multiple strip-shaped annular sanding belts 4.

[0046] After the cutting is completed, the geared motor 51 is started, which drives the corresponding rotating shaft 48 and sprocket 49 to rotate. The sprocket 49 drives the chain 50 and the second drive rod 52 to rotate. The second drive rod 52 drives the second frame plate 54 to move back and forth. The second frame plate 54 drives the feeding push plate 46 to move back and forth through the push rod 55. When the feeding push plate 46 moves forward, it can push the multiple strip-shaped annular sand belts 4 from the rotating roller 35 and the adjusting roller 36, so that the multiple strip-shaped annular sand belts 4 can fall into the collection box 34. When the feeding push plate 46 moves backward, it can reset the feeding push plate 46, thereby achieving the purpose of feeding multiple strip-shaped annular sand belts 4.
